IRVING, Texas — Jason Day fought through a rocky final round of the Byron Nelson Championship for a 2-over 72 on Sunday, but it was good enough to give the 22-year-old Australian the first win of his PGA Tour career.
Still, the 2010 Nelson will go down for the remarkable Tour debut by Jordan Spieth, a 16-year-old junior at a local high school.
Spieth was within three shots of the lead on the final nine holes, but dropped back into a tie for 16th. He shot a 2-over 72 in the final round, his highest score of the tournament. His 4-under 276 was six strokes behind Day.
The maturity and moxie Spieth the reigning U.S. Junior Amateur champion, showed was a surprise for someone who spent last week playing in the state high school tournament.
"It was awesome ... the entire round, the entire week," Spieth said. "Starting the week, I definitely would've taken a top-20, in a heartbeat."
Day was part of a seven-way tie for first after the opening round, a shot back after the second round and ahead by himself after the third.
His final round wasn't pretty: six bogeys, including one on 18 after hitting his approach into the water. He got lucky that playing partner Blake Adams, a 34-year-old PGA Tour rookie, also put his approach into the water and wound up taking a double bogey. That dropped Adams (72) into a tie for second with Brian Gay, who shot a 63 Sunday, and Jeff Overton (71).
LPGA Match Play — Twenty-three-year-old Sun Young Yoo won the Sybase Match Play Championship at Hamilton Farm on Sunday for her first LPGA Tour title, beating Angela Stanford 3 and 1 after dispatching top-seeded Jiyai Shin in the morning semifinals.
"My goal was to get past the first two days," Yoo said. "I did a lot better."
And she did it from the toughest quarter of the 64-player draw, beating No. 32 Karen Stupples, No. 5 Cristie Kerr, No. 12 Song-Hee Kim and No. 4 Yani Tseng before finishing off Shin 2 and 1 and No. 10 Stanford.
"It was tough," said Yoo, seeded 28th. "I tried to be a little more aggressive out there because it's match play. I think it worked out pretty good."
